For machine shops in a competitive global marketplace, keeping spindles running and making product is the only way to stay in business. Still, adding a new piece of equipment, even with the promise of improving the efficiency of your existing ones, may be a difficult sell to management.
In a perfect CNC world, the first part is always a good one. There’s no need for extra blanks or barstock. Setup times are only as long as is needed to swap out a few tools and load a new program. There’s never a crash, never the need to reprogram an inefficient bit of code. The operator just pushes the green button and out pops a finished workpiece minutes or hours later.
Do you have what it takes to raise your milling productivity to the next level? In addition to the requisite know-how, you need cutters and machine tools that will allow you to employ milling techniques that exceed what’s normally possible. Aided by the right hardware, you may soon be performing feats like pushing your feed rates to new highs and cutting harder materials than ever before.
Swiss-style machine tools can be a good choice for making complex parts. On the downside, however, Swiss machining itself has a reputation of being complex—and, therefore, more difficult to master than standard machining.
Technology came to the aid of Detroit Tigers management when they hoped to recapture some of the magic of the 1968 Detroit Tigers’ World Series-winning season. The 50-year anniversary celebration, held September 7-9, 2018, included on-field festivities in which the 16 surviving members of the 1968 team were presented with replicas of the World Series’ trophy.
At the Nirvana Machine Shop on planet Perfection, every workpiece is clamped to a custom-built fixture mounted on a dedicated machine tool. Each workpiece is dimensionally identical to the one before and the one after. All the fixtures are totally automatic—instantly positioning, clamping, machining, inspecting, and releasing the part with the ultimate precision.
Basic trends in modern manufacturing are driving growth in 3D optical metrology. “One is the highly complex and high-tech material that manufacturers are using today. For example, in the aerospace turbine blade market, they simply cannot touch the part like they used to—the surface finish of the material is too readily affected by any kind of contact metrology."
Celebrating its 80th year, Kennametal, the Latrobe, (PA), tooling manufacturer, says it has solved the age-long problem of tool stability when drilling in deep cavities, alongside tall shoulders, and past bulky fixtures. Reaching deep inside a workpiece to drill holes can be challenging.
Cutting tool technology continues to advance, and manufacturers can take advantage of a wide range of new cutting tool products. In this episode, Alan Rooks, Editor in Chief of Manufacturing Engineering magazine, talks with Tim Easton, National Sales Manager for NTK Cutting Tools.
Shops need both chemical and five-axis laser texturing capabilities to generate patterns that were once considered unattainable.
